Thick silicon tamp mat from Rocket Espresso with raised boarder and Rocket stamp.
Raised rim ensures stability and surface protection. A 90 degree rigid vertical fold ensures the map fits firmly onto your work surface and the mat makes it easier to tamp your coffee because you can support your bayonet on the mat while protecting your table top.
Note there is an edge on the rubber mat, so it should not be placed over a drawer opening. Here we would rather recommend the Rocket tamper mat without angle.
Stamper mat is in food grade silicon black.
